Recommendation 24
24
Not Addressed
Remediation costs for severe installation defects can significantly exceed the £20,000 guarantee limit.
Conclusion
Where guarantees are invoked, the repairs will likely in some cases cost more than the £20,000 covered by guarantee. TrustMark advises it should normally cost between £250 and £18,000 per home to correct the faulty installations, if it can be done before major damage occurs. However, in the worst case we are aware of it cost over £250,000 to fix the defects and resultant damage.51
